Patent GB-2039993-A (GB)
Title: Electromagnetic fuel injector
IPC: F02M63/00
Filed: 1979-12-18
Abstract: A stator (114) and a self-centering valve member (159) are mounted in a valve housing (142), the valve member including a ball valve (164). The ball valve (164) obturates an exit orifice (154) by sealing against a conical valve seat (150). Adjacent to the ball valve (164) and conical valve seat interface are vortex generating and metering orifices (149) for the tangential entry of fuel into a swirl chamber (151). The positions of the orifices (149), which are precisely sized to control flow rate, is used to determine the injector spray angle generated by the vortex of fuel as it leaves the injector. The conical surface of the valve seat produces vortex amplification to increase the swirl caused by the positioning of the entry orifices. The ball valve (164) is connected by a flexible stem (160) to a cup shaped armature (162) which is preferably coated with friction-reducing material (161). <IMAGE>

Title: Thermoplastic welding sleeve
IPC: F16L47/03
Filed: 1979-04-30
Abstract: A body sleeve (4) obtained by widening of a pipe is arranged on a mandrel on which spaced spirals (7) of a resistance wire (6) are wound. By heating the body sleeve (4), it is fixed onto the winding. An electric current circulating in the resistance wire causes the thermoplastic to melt and flow around the spirals for enclosing the latter completely by expansion. Further, the material forms projecting sections (8, 9) next to the winding. Hence, the spirals (7) are protected against accidentals shocks and the recessed end parts (5) of the inner wall which have been deformed inwards during manufacture require no further forming.
Patent GB-2045013-A (GB)
Title: A DC/AC converter
IPC: H02M7/538
Filed: 1980-03-03
Abstract: The converter includes a transformer (T) whose primary winding is fed by a battery via two power transistors (Q1, Q2) controlled alternately by means of an oscillator circuit A.

Each series circuit consists of a diode (D1; D2), the emitter- collector path of a transistor (T2; T1) and a resistance (R3, R4; R1, R2). In order for, e.g. transistor (Q2) to be turned on, transistor (T2) must be conductive (output D of oscillator A) and transistor (Q1) must be fully switched off so that the collector potential of transistor (Q1) is sufficient to render transistor (Q2) conductive via transistor (T2). <IMAGE>
